In my case it comes in 1/700 scale. I build ships that size because I live in a very small apartment. But there are times, when I'm looking at a reference picture and thinking, Yeah, I can do that ... and then discovering that No, no matter how hard I try and how small a Waldron punch I use, or how thin a diameter of wire, it's just not ... gonna ... work.
Case in point, rigging the cargo booms on my Liberty ship. I did OK with the larger blocks (pulleys), using down to about the .053 punch, thin sheet styrene and stretched sprue for the cables and lines. But then it came to the point where I was attempting the side guy blocks and tackle, finally decided that a .028 punch was the smallest I could use, and doing the math to find that would be a block more than 19-inches wide! Same with the MARSIG mast on the bridge deck, there's only so much my fumble fingers can do with 30-gauge wire and CA.
But it's still going to be one heck of a model when it's done ...
